A global meta-analysis of soil exchangeable cations, pH, carbon, and nitrogen with afforestation.
Afforestation, the conversion of non-forested lands to forest plantations, can sequester atmospheric carbon dioxide, but the rapid growth and harvesting of biomass may deplete nutrients and degrade soils if managed improperly. The goal of this study is to evaluate how afforestation affects mineral soil quality, including pH, sodium, exchangeable cations, organic carbon, and nitrogen, and to exa...
متن کاملGlobal patterns of the dynamics of soil carbon and nitrogen stocks following afforestation: a meta-analysis.
• Afforestation has been proposed as an effective method of carbon (C) sequestration; however, the magnitude and direction of soil carbon accumulation following afforestation and its regulation by soil nitrogen (N) dynamics are still not well understood. • We synthesized the results from 292 sites and carried out a meta-analysis to evaluate the dynamics of soil C and N stocks following afforest...
متن کاملDecade-scale changes of soil carbon, nitrogen and exchangeable cations under chaparral and pine
Four large lysimeters on the San Dimas Experimental Forest, each filled with similar parent material and planted with monocultures of native species in 1946, provide a unique opportunity to quantify short-term effects of plant species on soil properties. The four species under which soils were investigated are scrub oak (Quercus dumosa Nutt.) , chamise (Adenostoma fasciculatum Hook. and Am.), c...
متن کاملCarbon: nitrogen stoichiometry following afforestation: a global synthesis
Though carbon (C): nitrogen (N) stoichiometry has been widely studied in terrestrial ecosystems, little is known about its variation following afforestation. By synthesizing the results of 53 studies, we examined temporal and spatial variation in C: N ratios and in N-C scaling relationships of both the organic and the mineral soil horizons. Results showed that C: N ratios remained constant in t...
متن کاملInfluence of Exchangeable Cations on Water Adsorption by Soil Clays
little is known about the molecular mechanisms of soil– water interactions underlying this behavior. A considerThe interaction of water with the clay fractions ( 2 m) from two able amount of work has been conducted on specimen midwestern soils was studied using Fourier transform infrared (FTIR) spectroscopy and gravimetric methods. The soil clay fractions were clay minerals and their interactio...
